IMPROVEMENT IN BUTTON-FASTENERS.

Specification forming part of Letters Patent No. 153,282, dated July 21, 1874; application filed April 4, 1874.

To all whom it may concern:

' as are claimed as new and are desired to be secured by Letters Patent of the States.

My invention relates to that class of devices which are made use of for fastening buttons; and the nature thereof consists in certain improvements in the details of the construction of the same, hereinafter described.

In the accompanying plate of drawings, in which corresponding parts are illustrated by United similar letters, Figures 1 and 2 designate a piece of elastic metal, so bent as to form the arc of a circle, a, and having curvilinear ends I), bent either entirely within the circle, or extending beyond the circumference of the same.

The said curvilinear ends are of the form clearly shown in the drawings, and are'pro vided with indentations c, which fit within the eye of the button, and prevent the fastener from slipping. Fig. 3 designates a shell for the reception. of the fastener, having a slightly-convex base, o, and annular receptacle is, within which the circular part a is secured and held by the elastic force of the metal of which it is composed. In Figs. 4 and 5 the fastener, which consists of the are a and curvilinear ends I), is shown secured within the shell by the force of its own elasticity.

The shell presents to the body of the wearer a perfectly-smooth surface, thus preventing irritation.

I claim- A button-fastener composed of the concavoconvex flanged disk (I and the spring a, bent as described, the rim of the latter being covered by the flan ge. and all constructed in the manner and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day 01 February, 1874.
